VIENNA, Nov. 19 (Xinhua) -- The International Atomic Energy Agency (IAEA) do not find sufficient evidence to prove Syria is developing nuclear weapons, said a report circulated by IAEA Director General Mohammed ElBaradei to the agency's Board of Governors on Wednesday.

The four-page report introduces the latest verification and assessment on Syrian nuclear issues, but IAEA refuses to release the report to public, saying that this report is only submitted to the 35-member of the IAEA council, and will be discussed at next IAEA council meeting on Nov. 27.

Last September, Israeli troops blew down an establishment in a remote desert in eastern Syria. This May, the United States provided IAEA intelligence that the destroyed establishment is for developing nuclear explosive material and will be put into operation shortly. However, Syria keeps denying of secretly developing any nuclear weapons, on which IAEA has carried out investigations.

IAEA officials told reporters that ElBaradei has admitted in the latest investigation report that IAEA has found some characteristics that "are similar to what may be found in connection with a reactor site" in Syria's destroyed equipment. IAEA inspectors have also found "a significant number of uranium particles" in the samples taken from the site which was "produced as a result of chemical processing."

However, the report also points out that relevant evidence is not sufficient to draw a conclusion on the nature of Syria's destroyed establishment, therefore, IAEA calls on Syria and other states that may possess relevant information to cooperate with IAEA to provide further evidence and facilitate IAEA's investigation.

IAEA Director General Mohammed ElBaradei told a press conference in Dubai a day ago that the uranium particles found in Syria is not highly enriched to be used to fuel atomic bombs, and the origin of the nuclear traces found is not conclusive.
